To alt whom it may concern:

Be it known that I, SAMUEL WALTERS, a citizen of the United States, anda resident of Warren, in the county of Warren and State of Pennsylvania,have invented a new and Improved Car-Door, of which the fol lowing is afull, clear, and exact descrip- 'tion.

My invention relates generally to car door structures, and moreparticularly is directed to a new and improved construction wherebythedoor, when in closed position, lies flush with theoutside of the car. I

The principal object of my invention is to provide a new and improvedcar door embodying means whereby the door when in closed position willlie flush with the side of the car, means being provided for moving thedoor preparatory to opening it, suitable rails being provided wherebythe door may be rolled to uncover the opening, the door 'moving into a,position remote from the side of the door.

A further object of my invention is to provide a new and improved cardoor construction, the arrangement of the parts he ing such thatcommunimtion between the interior of the car and t e outside isprevented by the arrangement of the upper track on which the door moves,this track effectively closing the opening between the top of the doorand the door casing.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which like characters of reference indicatecorresponding parts in all the views, and in which- Figure 1 is a sideview of the car door in closed position Fig. 2 is a sectional view onthe line 22 of Fig. 1, the door being in open position; Fig. 3 is asimilar view, the position of the door previous to closing bcing shown;Fig. 4 is a similar view showing the door in closed position; Fig. 5 isa sec tional view on the line 55 of Fig. 2; Fig. 6 is a sectional Viewon the line 66 of Fig. 2; Fig.7 is a view showing the upper portion ofthe car door when in the position shown in Fig. 2; and Fig. 8 is abottoxnplan View showing the detail of the arrangement of the rail andthe shoe carried by the door.

Any suitable car comprising the side 2 is provided with an openingwhereby access to the interior is had, the opening being adapted to beclosed by the door 3 movably and slidably mounted in position, oppositesidewalls of the opening being provided with 1 pockets 4 into which theopposite side portions of the door are adapted to be seated when thedoor is closed, as shown particularly in Figs. 1 and 4.

The'outside of the car adjacent the top and bottom thereof is providedwith rails 5, 6, the lower rail 5 being positioned remote from the sideof the car for the greater portion of its length by means of suitablebraces 7, the end ortion 8 of this rail being bent and being broughtinto engagement with the side of the car adjacent the lower portion ofthe opening. The upper rail 6 is preferably positioned on a suitablesupport 9 secured to the side of the car in any desired manner, the railbeing bent similarly to the rail 5 and being substantially paralleltherewith. Each of the rails 5, 6 is prefei'- ably of T-shape in crosssection, as shown particularly in Fig. 5,the flanges of the rails beingin engagement with the braces 7 and the support 9 respectively by anysuitable means, such as bolts or screws 10.

Adjacent one end of the car door 3 and at the top and bottom thereof arethe shoes 11, 12 secured to the door in any suitable manner, preferablyby means of bolts 13, 14, the lower portion of the lower shoe'12 beingrecessed, as at 15, whereby it may embrace the or damaged "fromcontinued use. This shoeis also provided with a recess 100 adapted toembrace the rail 6 in a manner. similar to the shoe 19.. The oppositeend portion of the door, and adjacent the top and bottom thereof and onthe outside, is provided with fixed bearings 17 within which the rods18, 19 are rotatably mounted, the rods being preferably Separately madeand held to gothor in a manner substantially as follows: The lower endof the rod 18 is enlarged and provided with a substantially rectangularpocket 20, while the upper end 21 of the rod 19 is rectangular in crosssection and engages the pocket- 20, thereby providing for easyassemblage of the parts, turning of either rod insuring turning of theother rod by reason of such engagement. In order to turn the rod, asuitable lever 22 is pivotally mounted thereon at-23, the door beingprovided with a plurality of pockets 2 adapted to eceive the end of thelever in open or closed position, whereby the maintenance of suchposition is insured.-

The upper end of the rod 18 is provided with an off-set arm 25 which'dsin pivotal engagement. with a shoe 26 which shoe is provided with arecess 27 whereby it may embrace the T-shaped upper rail 6 and slidetherealongh The lower end of the rod 19 is provided with an ofi-set arm28 in pivotal engagement with the shoe 29 by means of a pin 30, the shoebeing provided with a recess 31 whereby it may-embrace and slide alongthe lower rail 5.

Referring particularly to Fig. 5, it will be noted that the lower end ofthe rod 19 extends beyond the lower portion of the door 3, while the uper portion of the rod 18' extends below t e top of the door 3, the sideof the door being preferably provided with a suitable pocket 32 wherebyease of operation and non-interference of the parts is 1 provided for.

From the above description it will be noted that the'rails 5, 6 arefixed in position to the side ofthe car, while the rods 18 19 arerotatably secured to the side of the door, it. being "clear thatifeither rod 18, 19 is turned, the door 3 will'be moved closer'to orremoved from'the side of the car," due to the off-set arms 25, 28 at theends of the rods 18, 19. Referring more particularly to Fig. 2 whichshows the door in open position, it will be noted that the door is'adja-. cent the side 2 of the car. In order to bring the door intoclosed position, it is moved to the left, the rods 18, 19 and the arms25, 28 thereof beingin the position shown in Fig; 3, at the end ofthetravel. By turning the lever 22 the rods will be "turned and the arms25, 28 will .swin the adjacent end of the door into the 00 et- 4 Fig.4:. In this position of the ugthe side wall of the opening, t e door bting then in closed position as shown in I outside of the door is flushwitht e outside arts, the

- will be noted that the portions 11, 11 of the '60 bottom of theseshoes are curved as at 11 so that when the end of the door movesjalongthe curved or bent portion of the tracks 5, 6, the curvature preventsbinding of the parts and provides for easy operation thereof. I

The door may be provided with any suitable form of locking device, thepreferred form embodying a hasp 40 having an opening therein engaging asuitable hook or staple 41 whereby withdrawal of the hasp 40 therefromis prevented. I y Of course, the particular size and'shape, as well asthe material of the difierent'elaments making up the structure of thecar door may be varied, depending upon the size and structure of thecars with which itisused, suchclianges, however, being com--prehendedwithin the spirit ofmy invention.

Having thus described my invention, I

nation with rails along which the door travels, comprising a pluralityof rods, one of 35 the rods being provided with a ocket which 7 engagesone end'of the otherro with'a nonrotative engagement, the end portionsof the said rods being provided with ofi'set arms, the said ofiset armsengaging shoes mountedon the said rails, 0"ne of the rods being providedwith a pivoted lever, and the door being provided with a' number ofpocketsany one ofwhich is adapted to engage the said lever, whereby theposition of the rods and the said offset arms is maintained.

In testimony whereof I have signed my name to this specification in thepresence of two witnesses.
